research scription

K.H. Kok is currently an Associate Professor in the Department of Microbiology, The University of Hong Kong. He is interested in the host-pathogen interaction, specifically the host antiviral responses. In 2011, he identified a host antiviral protein that can optimally induce the production of type-I interferon, an indispensable primary antiviral response during early infection. He continues to investigate the molecular mechanism of this host defense signaling pathway in the context of influenza A virus (IAV), herpes simplex virus (HSV), Epstein-barr virus (EBV) and human immunodeficiency virus (HIV) infection.
